Marking is a step or technique in MDA in which additional information, not within the semantic scope of the model itself, can be added to a model solely for use by automation later.
标记是MDA中的一个步骤或技术，在这个步骤当中，附加的信息（不包含在模型本身的语义范围中）能够被加入到模型中，在随后的自动过程中单独使用。
If your company works at either the modeling or infrastructure level, you can have a voice in defining the MDA.

To support these principles, the OMG has defined a specific set of layers and transformations that provide a conceptual framework and vocabulary for MDA.
为了支持这些原则，OMG已经定义了一系列的层次和转换，他们为 MDA提供了概念性的框架和词汇表。
As an emerging architectural standard, MDA falls into a long tradition of OMG support and codification of numerous computing standards over the past two decades.
作为一个新兴的体系架构的标准，MDA属于OM G支持的悠久传统和过去二十年中的众多计算机标准。
Since almost anything can be invoked and executed in a transformation created through the MDA Toolkit, there is no inherent transactional process monitoring.
虽然可以在MDA工具包创建的转换中调用并执行任何东西，但是还是不存在固有的事务流程控制。
As a result, an MDA tool may support transforming a model in several steps, from initial analysis model to executable code.
作为结果，一个MDA工具也许通过几个步骤支持转化一个模型，从最初的分析模型到可执行的代码。
By clarifying that these services are implementable in different environments and easily integrated, MDA represents our goal of universal integration: it becomes a global information appliance.
通过澄清这些服务可以在不同环境中实现并且很容易集成，MDA代表了我们的通用集成目标：成为一种全球性信息设施。
Many countries use ivermectin in a strategy called mass drug administration (MDA), which means that the entire population in an affected area is given the drug once or twice a year.
许多国家在一项叫做“大规模药物配给（MDA）”的战略中运用伊维菌素，该战略意味着在感染疾病的地区针对全部人口每年给药一两次。
A transformation, especially one created with the MDA Toolkit, is an example of custom software.
一个转换，特别是由MDA工具包创建的转换，是一个定制软件的实例。
Marking a model, in OMG MDA terminology, means tagging a model with extra information that is used by tools, and that is not appropriate to be captured in the model's semantics.
在OMGmda术语中，标记一个模型意味着利用工具所使用的，不适合从模型的语义中得到的额外信息来标记一个模型。
For example, a team working on object-relational data mapping may be using a modeling tool with a set of MDA transformations.
例如，一个进行关于对象的数据映射的团队可能会利用建模工具进行一组mda转换。
MDA is also developing and constructing a Test Bed that will allow it to conduct rigorous EKV tests at angles, speeds, and conditions that closely resemble operational scenarios.
